Sharp Announces Sales of DC Powered Air Conditioner, Other Products To Follow 45 45

AmiMoJo writes: Sharp has announced that sales of DC powered air conditioners will begin by the end of the year. Most appliances use the standard AC electricity supply in homes, but as solar panels become more common switching to DC can save on conversion losses. Solar panels produce DC, which is then typically converted to AC before being fed into the house's wiring, and then converted back to DC again by appliances. Sharp has announced that it intends to produce a range of DC powered appliances for home use.

San Francisco's Public Works Agency Tests Paint That Repels Urine 70 70

monkeyzoo writes: San Francisco is testing an ultra-water-repellant paint on wallls in areas fraught with public urination problems. The paint is designed to repel the urine and soil the offender's pants. "It's supposed to, when people urinate, bounce back and hit them on the pants and get them wet. Hopefully that will discourage them. We will put a sign to give them a heads up," said Mohammad Nuru, director of the San Francisco public works. A Florida company named Ultra-Tech produces the super-hydrophobic oleophobic nano-coating that was also recently used with success on walls in Hamburg, Germany [video] to discourage public urination. Signs posted there warn, "Do not pee here! We pee back!"

How Developers Can Fight Creeping Mediocrity 75 75

Nerval's Lobster writes: As the Slashdot community well knows, chasing features has never worked out for any software company. "Once management decides that's where the company is going to live, it's pretty simple to start counting down to the moment that company will eventually die," software engineer Zachary Forrest y Salazar writes in a new posting. But how does any developer overcome the management and deadlines that drive a lot of development straight into mediocrity, if not outright ruination? He suggests a damn-the-torpedoes approach: "It's taking the code into your own hands, building or applying tools to help you ship faster, and prototyping ideas," whether or not you really have the internal support. But given the management issues and bureaucracy confronting many companies, is this approach feasible?

Researchers Demonstrate the World's First White Lasers 75 75

An anonymous reader writes: Scientists and engineers at Arizona State University, in Tempe, have created the first lasers that can shine light over the full spectrum of visible colors. The device's inventors suggest the laser could find use in video displays, solid-state lighting, and a laser-based version of Wi-Fi. Although previous research has created red, blue, green and other lasers, each of these lasers usually only emitted one color of light. Creating a monolithic structure capable of emitting red, green, and blue all at once has proven difficult because it requires combining very different semiconductors. Growing such mismatched crystals right next to each other often results in fatal defects throughout each of these materials. But now scientists say they've overcome that problem. The heart of the new device is a sheet only nanometers thick made of a semiconducting alloy of zinc, cadmium, sulfur, and selenium. The sheet is divided into different segments. When excited with a pulse of light, the segments rich in cadmium and selenium gave off red light; those rich in cadmium and sulfur emitted green light; and those rich in zinc and sulfur glowed blue.

Research: Industrial Networks Are Vulnerable To Devastating Cyberattacks 52 52

Patrick O'Neill writes: New research into Industrial Ethernet Switches reveals a wide host of vulnerabilities that leave critical infrastructure facilities open to attackers. Many of the vulnerabilities reveal fundamental weaknesses: Widespread use of default passwords, hardcoded encryption keys, a lack of proper authentication for firmware updates, a lack of encrypted connections, and more. Combined with a lack of network monitoring, researchers say the situation showcases "a massive lack of security awareness in the industrial control systems community."

Beyond Safety: Is Robotic Surgery Sustainable? 41 41

Hallie Siegel writes: The release last week of the study on adverse events in robotic surgery led to much discussion on the safety and effectiveness of robotic surgical procedures. MIT Sloane's Matt Beane argues that while the hope is that this dialogue will mean safer and more effective robotic procedures in the future, the intense focus on safety and effectiveness has compromised training opportunities for new robotic surgeons, who require many hours of 'live' surgical practice time to develop their skills. Beane says that robotic surgery will likely continue to expand in proportion to other methods, given that it allows fewer surgeons to perform surgery with less trauma to the patient, but no matter how safe we make robotic surgical procedures, they will become a luxury available to a very few if we fail to address the sustainability of the practice.

Obama's New Executive Order Says the US Must Build an Exascale Supercomputer 161 161

Jason Koebler writes: President Obama has signed an executive order authorizing a new supercomputing research initiative with the goal of creating the fastest supercomputers ever devised. The National Strategic Computing Initiative, or NSCI, will attempt to build the first ever exascale computer, 30 times faster than today's fastest supercomputer. Motherboard reports: "The initiative will primarily be a partnership between the Department of Energy, Department of Defense, and National Science Foundation, which will be designing supercomputers primarily for use by NASA, the FBI, the National Institutes of Health, the Department of Homeland Security, and NOAA. Each of those agencies will be allowed to provide input during the early stages of the development of these new computers."

Nokia Announces OZO 360-Degree Camera For Filming Virtual Reality 18 18

New submitter Sepa Blackforesta writes: Nokia has unveiled Ozo, a next-generation camera for capturing audio and video in 360 degrees. It is built for professional content creators and the company hopes the camera will become the leading device for shooting virtual-reality experiences for Hollywood. A formal launch and price announcement is planned for the fall. A Nokia press release reads in part: "OZO captures stereoscopic 3D video through eight (8) synchronized global shutter sensors and spatial audio through eight (8) integrated microphones. Software built for OZO enables real-time 3D viewing, with an innovative playback solution that removes the need to pre-assemble a panoramic image - a time-consuming process with solutions currently in the marketplace. OZO's filmed content can be published for commercially available VR viewing hardware such as head mounted displays (HMDs), with immersive, full 360-degree imaging and spatially accurate original sound. OZO also integrates into existing professional workflows and works with third-party tools, dramatically simplifying content production at all stages."

Genetically Modified Rice Makes More Food, Less Greenhouse Gas 211 211

Applehu Akbar writes: A team of researchers at the Swedish University of Agricultural Sciences has engineered a barley gene into rice, producing a variety that yields 50% more grain while producing 90% less of the powerful greenhouse gas methane. The new rice pulls off this trick by putting more of its energy into top growth. In countries which depend on rice as a staple, this would add up to a really large amount of increased rice and foregone methane.

Replacing Silicon With Gallium Nitride In Chips Could Reduce Energy Use By 20% 80 80

Mickeycaskill writes: Cambridge Electronics Inc (CEI), formed of researchers from the Massachusetts Institute of Technology (MIT), claim semiconductors made of gallium nitride (GaN) could reduce the power consumption of data centers and consumer electronics by 20 percent by 2025. CEI has revealed a range of GaN transistors and power electronic circuits that have just one tenth of the resistance of silicon, resulting in much higher energy efficiency. The company claims to have overcome previous barriers to adoption such as safety concerns and expense through new manufacturing techniques. "Basically, we are fabricating our advanced GaN transistors and circuits in conventional silicon foundries, at the cost of silicon. The cost is the same, but the performance of the new devices is 100 times better," Cambridge Electronics researcher Bin Lu said.

Microsoft Edge On Windows 10: the Browser That Will Finally Kill IE 213 213

An anonymous reader writes: Windows 10 launches today and with it comes a whole new browser, Microsoft Edge. You can still use Internet Explorer if you want, but it's not the default. IE turns 20 in less than a month, which is ancient in internet years, so it's not surprising that Microsoft is shoving it aside. Still, leaving behind IE and launching a new browser built from the ground up marks the end of an era for Microsoft. “Knowing that browsing is still one of the very top activities that people do on a PC, we knew there was an opportunity, and really an obligation, to push the web browsing experience and so that’s what we’ve done with Microsoft Edge," Drew DeBruyne, director of program management at Microsoft told VentureBeat.

Tools Coming To Def Con For Hacking RFID Access Doors 22 22

jfruh writes: Next month's Def Con security conference will feature, among other things, new tools that will help you hack into the RFID readers that secure doors in most office buildings. RFID cards have been built with more safeguards against cloning; these new tools will bypass that protection by simply hacking the readers themselves. ITWorld reports that Francis Brown, a partner at the computer security firm Bishop Fox, says: "...his aim is to make it easier for penetration testers to show how easy it is to clone employee badges, break into buildings and plant network backdoors—without needing an electrical engineering degree to decode the vagaries of near-field communication (NFC) and RFID systems."

What Federal Employees Really Need To Worry About After the Chinese Hack 114 114

HughPickens.com writes: Lisa Rein writes in the Washington Post that a new government review of what the Chinese hack of sensitive security clearance files of 21 million people means for national security is in — and some of the implications are quite grave. According to the Congressional Research Service, covert intelligence officers and their operations could be exposed and high-resolution fingerprints could be copied by criminals. Some suspect that the Chinese government may build a database of U.S. government employees that could help identify U.S. officials and their roles or that could help target individuals to gain access to additional systems or information. National security concerns include whether hackers could have obtained information that could help them identify clandestine and covert officers and operations (PDF).

CRS says that if the fingerprints in the background investigation files are of high enough quality, "depending on whose hands the fingerprints come into, they could be used for criminal or counterintelligence purposes." Fingerprints also could be trafficked on the black market for profit — or used to blow the covers of spies and other covert and clandestine officers, the research service found. And if they're compromised, fingerprints can't be reissued like a new credit card, the report says, making "recovery from the breach more challenging for some."
